IMPROVEMENT IN HARVESTER-RAKES.

Specljication forming part of Letters Patent No. 98,266, elated August 3, 1869; cmtedatetl July 23, 1869.

To all whom lt may concern:

Be it known that I, JULIUS WILOKE, of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Im-v provement in Automatic Rakes for Reaping Machines 5 and I do declare that the following is a true and accurate description thereof7 reference being had to the accompanying drawings, and to the letters of reference marked thereon, and being a part of this specification, in which- Figure 1 is an elevation of the right side of the apparatus, with the lower part of the standard broken out to show the position of the rake in commencing its sweep. Fig. 2 is a rear elevation of the apparatus, partially in section. Fig. 3 is a plan view of the table, with the' varying positions of the rake thereon shown by the lines. Fig. 4 is a side elevation and vertical section of the crank and cranked pinion, showing the position of the stop y when engaged with a recess on the pinion-shaft I. Fig. 5 shows the revolving guide-sleeve M, carrying the rake-rod R, and the method of its operation, the position of the rake when commencing its sweep being shown at K, and when completed, in outline at K. Fig. 6 is a side and face view'of the double clutch N, sliding on the shaft S; and Fig. 7 is a horizontal section ot' the female reverseclutch in two sections, of the F section of the same.

Similar letters refer to corresponding parts in each figure.

The object of this invention is to construct an apparatus which, when sufficient grain to form a sheaf has been cut, and is lying on the rake-table ot a reapingmachine, will automatically rake the same to the rear of the table, and deposit it on the ground, ready for bind- Ing.

'lhe apparatus is designed to be attached to reaping-machines of the ordinary mode of construction, and be operated by the same.

To accomplish this purpose, upon the corner ot the machine, near the rear inner end of the sickle-bar, I erect apost, I, which supports a bracketed standard, A A'. Properly journaled into and passing through the same, is a shaft, S, carrying a pulley, H, driven by a belt E and F, and endview or chain from a pulley on a transverse shaft i in the reaper proper. The standard A has cast with it a geared segment, J, describing an arc of about forty-tive degreesg'at one sideof the rear end of which 1s an lnclined plane, T. Loosely sleeved on the shaft S is a crank, D,

with a lug, d, opposite its arm, and whose hub is provided with recesses e, Fig. 4. A double reverse-clutch, N, Fig. 6, is also'sleeved upon the shaft, having a ange, f, recesses a a', and vribs e' c', which last engage with the recesses e e in the hub of the crank D, to prevent its revolving with the shaft when out of gear.

E F, Fig. 7, form ay clutch, embracing and moving the clutch N, by means of its flange f engaging with arecess halved into the flanges of the sections E F, which are' held together, and moved back and forth, by links from the clutchlever G, embracing semicircular studs g on the peripheres of their iianges.

The section F is provided with a transverse slot, d', on its end, which engages with the lug tl on the hub of the crank D.

A spiral spring, O, between 'the Standard and the clutch N, prevents its recesses a a from embracing a pinna, Fig. 2, through the shaft S, except when drawn into gear by the surrounding clutch E F through the clutchlever G.

Journaled into the upper end of the crank D is a shaft, I, Fig. 2, carrying a pinion, B, and crank C, Fig. 4. The outer end of the cra'nk is formed with a square shoulder on its wrist-end, which has two guide-holes te :e drilled through it, through which pass rods, connect` ing the cross-bars c and o', the inner one carrying a stud or lift-pin, z, and the outer one a stop-pin, y, which is caused to enter a recess in the shaft P by means of the spiral springs s s, between the bar c and theinner side of the shoulder, preventing the shaft frommevolving,

except when the crank D in its revolution l causes the pin z to be lifted as it passes up the inclined plane T, causing the stop-pin y to be withdrawn from the shaft, which makes one complete revolution through its pinion B engagin g with the segment J. I

M is a sleeve, cast with a boss on one side,

which is transversely bored to receive the shaft S, upon which it revolves, and has a u is held on the rod by a pin oricapon the end of the same, and between its inner end and the shoulder on the rod (formed by turning it down) is a spiral spring, w, arranged to press the rod down toward the table L while raking.

At the lower end of the rod is hinged a rake,

K, which is forced against the snrfaceof Ythe table L by the crank C pressing the sleeve "u on the rod against the spiral spring w, and the A shoulder at that end of therod, and the bellcrank lever a b, connected to'the flange "at the bottom of the sleeve'M bythe linkc.

The rod and rake are compelled to describe a curve, correspondingwith that of fthe table L, byineans of the pin rjengaging With 'the spiral slot 'mofthe sleeve M.

Having thusnauied'the various parts of in y invention, Iwill now explain the method `of its operation, lpremising, however, that lit 'is attached to a'reapngmachine linlthfemaniier indicated,`

The rake K being` uppermost, the springO causes the recess d! in the clutch F to engage with the lug d on the rakecrank `D,and'holds the same stationary, while `the shaft iscon` "tnually revolved hy a belt or 'endless lchain from a transverse shaft inthe reaper, acting o'n the driving-wheel H, Then,perceivingthat sufficient grainto form a sheafhasben cut,V

and is lying on the frontot' the platform, by means of the clutch-lever G the operator withdraws the clutch F from the stud d on the crank D. At'the same time recess u of the,

clutch N engages withthc pinn on the shaft,` when motion is communicated to it andthe crankD, the ribs c' e Vbeing butpartially withdrawn from the recesses e e in the hub of the crank.

The crank continuing its revolution, the lift pin z, advancing up the inclined plane T, causes the stop y on the cross-bar t" tobe withdrawn from the pii1ion-shaft P, whoseipinion lithen engages with thefgeared segment J, andupon which it makesonerevolution with itscrank (J, which in its first half revolution presses down the rake-rod Rthrongh'the guidesleeve M. The pin r in the rod, working in the spiral' a vertical position.

`groove m, causes the rod to make one-fourth of a revolution on its axis, carrying the rake K with it, and which is keptin a horizontal position in its sweep by the bell-crank levers b and a, and the link c, connected to the flange at the lower end of the guide-sleeve M.

The rake having swept the grain ofi' the table, and the pinion -B completed its revolution, and passed beyond the segment J, the

springs w cause the stop y to enter the recess in the shaft P, which is then held stationary,

while in the second half revolution of the crank Cthe rake-rod Ris drawn back up through the guide-sleeve M, while the pin o' causes it 4torotate back one-fourth of a revolution, when the rake K is again parallel with the cutterbar at the front of the table, after arriving at At this timethe spring "O throws the clntch `F into gearwith fit, and holds it fast, while `tliejclutch N isthrownout o'f gear with `the shaftS, which continues to Vrevolve' until the operator again 4finds suiicient 'grain on the table tol'orrn a sheaf, when'the operation is repeated.

What I claim as 1nyi11vention,and desire to secure by Letters Patent, is l 1. The post I, bracketed standard A A', `with its geared segmentJ and inclined :plane T, the `shaft S and drivingpull'ey H, crank D, iitted with lug d and recesses e e on its liiib,gand

guideholes as w on fits wrist-end, in connection4 `with the bars n v',stop-pin/,lifbpin z,\and springs ss, thepinion B, pinion-shaft P ,crank 0, and crank-sleeve u, substantially as dc- "scribed, and for the purposes set i'orth.`

2. The guide-sleeve M, providedwith spiral 4 groove m, `the rake K, and `rake-rod ;1R,:pro vided with spring 2c, `pin r, and bellcrank :levers a and b, and link c,`inconnectiontwith "thetlangerof the sleeve M,or its equivalent, loperating in `the manner described,andfor thefpurposes specified.

3. The double clutch N, provid edwithitlange f, ribs e e, and recess n', in connection with the pin iz., the sectional clutch E F,;provided`with As'emicircular coupling-studs g, andrecessesd, clutch-spring() and clutch-lever G, or their equivalents, substantially as described, and operating for the-purposes specified. 1 l
